/**
 * This interface is provided by the RoutingEngine of CTP. It provides two
 * commands that enables an external component (e.g., the ManagerC component)
 * to stop the RoutingEngine when the Ultra Low Power Mode (ULPM) of DISSense
 * begins. The key difference between the two commands is
 * that the reset() command is called when the next active phase has a Resynchronization Interval (RI) scheduled. It resets
 * the state of the RoutingEngine such that, when the RI takes place, a new resynchronization is made and the values carried by the Implicit Backward Channel (IBC) can be
 * shared. The pause() command is called when the next phase has no RI scheduled
 * (GTI -> DCI transition). As opposed to reset(), this command just pauses the
 * RoutingEngine (i.e., it disables beacons transmission and reception).
